Running Magento 2.2.8 - Magento runs on Developer mode

Varnish version 4.1.11

Installed Varnish successfully on Apache 2.4

I set VARNISH_LISTEN_PORT=80 at /etc/sysconfig/varnish

With out-of-the-box settings in /etc/varnish/default.vcl Varnish works on 127.0.0.1 (I see X-Varnish header when pinged with CURL), except on my actual domain and therefore store. The https version of my store is the default one (naturally).

When I probed with

curl -I http://example.com 

Surprisingly, Varnish headers showed. So now, I went ahead and disabled "Upgrade insecured requests" from Magento admin. However, this caused http versions of my store pages to not load at all.

Exported configuration file from Magento admin for Varnish 4. Replaced Varnish default.vcl with the exported file.
Now Varnish does not work for 127.0.0.1 either (nor for my actual domain name neither with http or https)

I am aware of the relative path "/pub" being added to the Magento-exported default.vcl issue. I removed the /pub and this did not solved my issue. I removed the whole probe = health check altogether and still no X-Varnish headers (nor X-Magento-Cache-Debug header).

grep -iw listen /usr/local/apache/conf/httpd.conf

Apache listens on 0.0.0.0:8080 and 0.0.0.0:443

grep VARNISH_LISTEN_PORT /etc/sysconfig/varnish

VARNISH_LISTEN_PORT=80

There seem to be plenty of information about configuring Varnish with Magento and I read a whole lot of it, spent the last two days on this and I'm hitting a wall.

What am I missing here? What do I not understand?

Can anyone share their experience in detailed steps in successfully configuring Varnish 4.x with Magento 2.2.x?

How did you successfully configured Varnish (4.1) with Magento 2.2.x?

I appreciate your time answering. Thanks!

Here is the latest version of default.vcl I tried (best one so far, same not-working-effect):

 vcl 4.0;

import std;
# The minimal Varnish version is 4.0
# For SSL offloading, pass the following header in your proxy server or load balancer: 'X-Forwarded-Proto: https'

backend default 
 .host = "127.0.0.1";
 .port = "8080";


acl purge 
 "127.0.0.1";


sub vcl_recv woff2

sub vcl_hash 
 if (req.http.cookie ~ "X-Magento-Vary=") 
 hash_data(regsub(req.http.cookie, "^.*?X-Magento-Vary=([^;]+);*.*$", "1"));
 

 # For multi site configurations to not cache each other's content
 if (req.http.host) 
 hash_data(req.http.host);
 else 
 hash_data(server.ip);
 

 # To make sure HTTP users don't see SSL warning
 if (req.http.X-Forwarded-Proto) 
 hash_data(req.http.X-Forwarded-Proto);

sub vcl_deliver
